question on adding new material

[baozai]

Hi:

I followed the tutorial on adding new material. I wrote the new rule of judging criterion with the name 'TSCriterion.cpp', and a new material has relation to this rule with the name 'TSLimitStateMaterial.cpp'.
I wrote the first part of the cpp following the way PinchingLimitStateMaterial.cpp, so I had

void *
OPS_PinchingLimitState(void) {
xxxxxxx
}
in 'TSLimitStateMaterial.cpp' and

void *
OPS_TSCriterion(void)
{xxxxxxx
}
in 'TSCriterion.cpp' .

Then I wrote the

} else if (strcmp(argv[1],"TSLimitStateMaterial") == 0) {
void *theMat = OPS_TSLimitStateMaterial();
if (theMat != 0)
theMaterial = (UniaxialMaterial *)theMat;
else
return TCL_ERROR;
in 'TclModelBuilderUniaxialMaterialCommand.cpp' for calling 'TSLimitStateMaterial.cpp' and

else if (strcmp(argv[1],"TSCriterion") == 0) {
void *theRSC = OPS_TSCriterion();
if (theRSC != 0) {
theCurve = (LimitCurve *)theRSC;
} else
return TCL_ERROR;
}
in 'TclLimitState.cpp' for calling 'TSCriterion.cpp'

Then when I Rebuilt the OpenSees, I got the following error:
Error 1690 error LNK2019: unresolved external symbol "void * __cdecl OPS_TSLimitStateMaterial(void)" (?OPS_TSLimitStateMaterial@@YAPAXXZ) referenced in function "int __cdecl TclModelBuilderUniaxialMaterialCommand(void *,struct Tcl_Interp *,int,char const * *,class Domain *)" (?TclModelBuilderUniaxialMaterialCommand@@YAHPAXPAUTcl_Interp@@HPAPBDPAVDomain@@@Z) material.lib

It seems there is something wrong with the command I wrote in TclModelBuilderUniaxialMaterialCommand.cpp and TclLimitState.cpp. But I did think I wrote the new commands as the existed ones. Could anybody help me with this?
Thank you and best wishes.

the material you are writing appears to need more than the typical functions .. it will not work using the .dll approach as these functions are not defined in the api .. you will need to add to the main .exe instead . which means downloading the whole source code using svn, adding the material to the material project and makking changes to the TclModelBuilderUniaxialMaterialCommand.cpp file

Hi, Frank, thank you very much for replying.

Sorry, please let me explain the steps I did first: the material I wrote is added to the whole source code which downloaded from website. It is R5621. I added TSCriterion.h and TSCriterion.cpp to the folder 'limitCurve', and I added TSLimitStateMaterial.cpp and TSLimitStateMaterial.h to the folder 'limitState'. Then I added relative commands in TclLimitState.cpp and TclModelBuilderUniaxialMaterialCommand.cpp. And after that, I got the errors as posted.

I am sorry I didn't get your reply very well. Is that mean that only adding the commands in the TclModelBuilderUniaxialMaterialCommand.cpp is not enough? If so, what should I do for making changes for TclModelBuilderUniaxialMaterialCommand.cpp? I think for the material PinchingLimitState, it is also only add the the judging commans in TclModelBuilderUniaxialMaterialCommand.cpp, and for RotationShearCruve, it is also only add commands in TclLimitState.cpp. And they worked. Would you please explain a little bit more on your comments? I am very appreciate for your help.

can't say off the top of mmy head. build OpenSees without any modifications to make sure it compiles. if it compiles then add your code in stages.

Hi, Frank, Thank you for the reply. I did compile OpenSees successfully before adding the code. May I send my source code and relative changes in other files to you to see if you have time to have a look at it? I appreciate the help.

i am busy through next week .. conference in Alaska .. after that you can send

Hi, Frank. Thank you very much for this help. Have a good time in Alaska.
